QUESTION
I'm doing a project on Shiny where there are several drop-down menus. The options contained in the menus are stored in a data frame and when running the app you have the option to add more data to the data frame. The behavior I expected was that the options in the drop-down menu would automatically update with changes in the data frame, but this doesn't happen.
Is this possible to be done in Shiny? If yes, how?
Here's a code with an example of how I'm doing.
...ANSWER
Answered 2021-Jun-15 at 12:54You have several issues here.
- The second
selectInput
depends on the first one, so you need to update it also to display the updated dataframe. - It would be best to create a
reactiveValues
object as the dataframe to be updated. - You need an
observeEvent
to update the secondselectInput
, whenever the first one is updated.
Lastly, dataframe is updated only when the actionButton
on the second tab is clicked - to avoid updating dataframe while typing long text.

QUESTION
Problem
I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.
Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.
This is what I tried so far:
- A simple
data.replace('\'', '\"')
is not possible, as the "text" fields contain tweets which may contain ' or " themselves. - Using regex, I was able to catch some of the instances, but it does not catch everything:
re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
- Using
literal.eval(data)
from theast
package also throws an error.
As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.
Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

that are causing the problem are only in the tweets and desciption

QUESTION
I'm having an issue with storing the original file name both in the database and in disk storage. The file saves correctly in the database and in the Nova backend, but in the disk storage is just saves as a random string.
In the database: my-user-friendly-file-name.pdf
In the disk storage: kfnakfncanjnaskdmkasniodanwjioeocniosandoaisndcacs.pdf
I have followed the docs, and it seems the below code should work but it doesn't.
...ANSWER
Answered 2021-Jun-08 at 12:37So just as @ceejayoz said I ended up storing an extra column for the original file name and then call that in your code where needed, in my case emailing out attachments.
QUESTION
Guys this sounds like a simple problem, but I'm having trouble solving it. Basically, the function desenhaFaceTot() allows drawing three dices on three different canvas through a button and assigning the numArray value to each dice drawing the dice points according to the number that came out (example: n = 5 draws five points) and then arranges the dices in ascending order this does everything well the problem is that: I wanted to change the value of the first dice (the smallest number in the array) by pressing the canvas in the alterarNumero() function and arrange it later instead my program changes the value of any of the dice.
Example of an operation I wanted to happen
Dices:
1 3 4
after pressing the first canvas onclick: (the number that came out is, for example, six)
3 4 6
What happens in my code instead of changing the value of the first dice changed any of the dice in the case changed for example the dice number 3 and put the number 6
1 3 6
(half the code is drawing stuff on the canvas)
...ANSWER
Answered 2021-Jun-08 at 01:22New Answer based on comment. When you are changing n
you are changing it on the original array before the sort. The sort does not change the order of the original array that is above it. So as you can see here in this console log I have logged numArray
before the sort and after. I also logged n
so you can see what's happening.
QUESTION
I'm making a bubble map similar to this one: https://observablehq.com/@d3/bubble-map
Everything is working except that my smaller bubbles are not always showing on top of the larger ones. I can't see why, as I've sorted the data before drawing the circles. Can anyone see what I'm doing wrong?
Here is a plunker: https://plnkr.co/edit/JKWeQKkhN2TQwvNZ?open=lib%2Fscript.js
Code is below. The other files are too large for stack overflow but can be accessed via the Plunker.
...ANSWER
Answered 2021-Jun-08 at 00:26I would suggest you to split your data to a couple separate datasets grouped by size and create distinct group (g
element) for each one. This will also fix issues with circles highlighting.
I slightly updated your plunker to make it work as described (check the lines 91-167) https://plnkr.co/edit/rayo5IZQrBqfqBWR?open=lib%2Fscript.js&preview
Also check the raise and lower methods. They might be a good replacement for your moveToFront
and moveToBack
methods.

Answered 2021-Jun-06 at 15:31If you are using is C++ and glm, then glm::mat4 model(1.0f);
constructs an identity matrix.
If you are using cglm then mat4 model = {1.f};
does not initialize an identity matrix. mat4
is a structure, but not a class with a constructor.
You have to use glm_mat4_identity
:
mat4 model = {1.f};
mat4 view = {1.f};
mat4 proj = {1.f};
QUESTION
As stated in the title. I managed, with the help of another user, to finish a script that creates emails with one or multiple attachments. It works like this.
First, the script runs through all the customers names and selects the unique values. After that, it filters one by one. If there is one row for Client 1, this means that the outlook email will have only one attachment; if there are 2 rows, then two attachments, so on and so forth.
My current problem is that the vba is multiplicating the attachments. If client 1 has three rows, it will add the attachments three times, for a total of 9; the goal is to add one one attachment per row.
Can you spot the issue?
...ANSWER
Answered 2021-Jun-03 at 17:40Seems like you are missing to change from "D"
to "B"
in the last part when you set the range for the Set attach_range =

). Changing this and your code works fine for me.

QUESTION
I'm using fortify for authentication stuff, however I need to change the text in the "Reset Password" email template automatically sent by fortify. I can't find a way to achieve this.
Also is it possible to make the template editable from Nova ? I have a MailTemplate Resource in Nova to allow changing email template from Nova, but I can't achieve this for the "Reset Password email" since it's sent by fortify and can't find a way to control it.
...ANSWER
Answered 2021-May-28 at 09:38Fortify uses the core notification system from Laravel to send the password reset email. The specific file responsible for this is the PasswordReset.php
file located at Illuminate\Auth\Notifications
.
The simplest way to customise the email that is sent would be to make a copy of the PasswordReset
file and save it to your project somewhere (e.g. App\Notifications
) with a different name (optional).
Once copied and you've customised it to your liking, you'll then need to overwrite the sendPasswordResetNotification
method on your User
model which is inherited from the CanResetPassword
trait on the Authenticatable
class.
